  • An Introduction to Buffing and Polishing
    AN INTRODUCTION TO BUFFING AND POLISHING 7696 Route 31, Lyons NY 14489 http://www.caswellplating.com (315) 946-1213 Page 1 To Order Call: 315-946-1213 AN INTRODUCTION TO BUFFING & POLISHING Buffing and polishing using wheels and ‘compounds’ is somewhat like using wet and dry sanding paper, only much faster. Instead of using ‘elbow grease’ you will be using the power and speed of an electric motor. The edge, or face, of the wheel is the ‘sanding block’, which carries a thin layer of compound’ which is the sandpaper. Varying types of wheel are available, and the different grades of com- pound are scaled similar to sandpaper. The compounds are made from a wax substance which has the different abrasive powders added to it. When this hard block is applied to the edge of a spinning buffing wheel, the heat from the friction melts the wax, and both wax and abrasive are applied in a thin slick to the face of the wheel. The objective of buffing and polishing is to make a rough surface into a smooth one and, of course, each work piece will be in a different condition, so will need different procedures. Imagine the surface magnified thousands of times, it will look like jag- ged mountains and valleys. By repeated abrasion, you are going to wear down those mountains until they are old, soft, rolling hills! Then they will not dissipate the light, but reflect it. It is the reflection that makes the buffed part appear shiny. TRICKS OF THE TRADE Repairing small dents. Sand the inside of the part with emery paper.

  • Metallographic Preparation of Stainless Steel Application Notes
    Metallographic preparation of stainless steel Application Notes Corrosion resistant steels contain at least 11% chromium and are collectively known as “stainless steels“. Within this group of high alloy steels four categories can be identified: ferritic, martensitic, austenitic, and austenitic-ferritic (duplex) stainless steels. These categories de- scribe the alloy’s microstructure at room temperature, which is largely influenced by the alloy composition. The main characteristic of stainless steels is their corrosion resistance.

  • Improvement of Punch and Die Life and Part Quality in Blanking of Miniature Parts
    Improvement of Punch and Die Life and Part Quality in Blanking of Miniature Parts DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Soumya Subramonian Graduate Program in Mechanical Engineering The Ohio State University 2013 Dissertation Committee: Dr.Taylan Altan, Advisor Dr.Blaine Lilly, Advisor Dr.Gary L.Kinzel Dr.Jerald Brevick Abstract Blanking or piercing is one of the most commonly used sheet metal manufacturing processes in the industry. Having a good understanding of the fundamentals and science behind this high deformation shearing process can help to improve the tool life and blanked edge quality in various ways. Finite Element Modeling of the blanking process along with experimental testing is used in this study to study the influence of various process parameters on punch and die life and blanked edge quality. In high volume blanking and blanking of high strength materials, improving the tool life can save not only tool material but also change over time which can take up to a few hours for every change over. The interaction between punch, stripper plate and sheet material is first studied experimentally since a fundamental understanding of the behavior of these components at different blanking speeds is very essential to design robust tooling for high speeds. A methodology is developed using the experimentally obtained blanking load and FEM of blanking to obtain flow stress data of the sheet material at high strains and strain rates. This flow stress data is used to investigate the effects of various process parameters on tool stress and blanked edge quality.

  • Chapter 2 the Preparation of Samples for Ore Microscopy
    CHAPTER 2 THE PREPARATION OF SAMPLES FOR ORE MICROSCOPY 2.1 INTRODUCTION Th e preparation of polished surfaces free from scratches, from thermal and mechanical modification of the sample surface, and from relief is essential forthe examination, identification, and textural interpretation of ore minerals using the reflected-light microscope. Adequate polished surfaces can be pre­ pared on many types of materials with relatively little effort using a wide variety of mechanical and manual procedures. However, ore samples often present problems because they may consist ofsoft, malleable sulfides or even nati ve metal s intimately intergrown with hard, and som etimes brittle, sili­ cates, carbonates, oxides, or other sulfides. Weathering may complicate the problem by removing cements and interstitial minerals and by leaving sam­ ples that are friable or porous. Delicate vug fillings also cau se problems with theiropen void spaces and poorly supported crystals.Alloys and ben eficiation products present their own difficulties because of the presence of admixed ph ases ofvariable properties and fine grain sizes. In this chapter, the general procedures ofsample selection and trimming, casting, grinding, and polish­ ing (and, in special cases, etching) required to prepare solid or particulate samples for examination with the ore microscope are discussed. The prepara­ tion ofthese polishedsections, and also polished and doubly polished thin sec­ tions, which are useful in the study of translucent or coexisting opaque and translucent specimens, is described. These are matters about which all stu­ dents of reflected-light microscopy should be aware, ideally through per­ sonal experience. lReliej is the un even surface of a section resulting from so ft ph ases being worn away mor e than hard ph ases during polish ing.

  • Abrasive Flow Machining: a Case Study
    Journal of Materials Processing Technology, 28 ( 1991 ) 107-116 Elsevier Abrasive flow machining: a case study Larry Rhoades President, Extrude Hone Corp., P.O. Box 527, 8075 Pennsylvania Ave., Irwin, PA 15842, U.S.A. INTRODUCTION Abrasive Flow Machining (AFM) is used to deburr, polish or radius surfaces and edges by flowing a semisolid abrasive media over these areas. The process embraces a wide range of feasible applications: from critical aerospace and medical components to high production volumes of parts. AFM can reach even the most inaccessible areas, processing multiple holes, slots or edges in one operation. Advances in media formulation and tool design coupled with new capabilities in processing and automation have established the abrasive flow process as a way of satisfying tough marmfaetudng requirements economically and productively. The AFM process can be used in a wide range of finishing operations. It can process many areas on a single workpiece or multiple parts simultaneously. Inaccessible areas and complex internal passages can be finished economically and productively. Automatic AFM systems can handle thousands of parts per day, greatly reducing labor costs by eliminating tedious hand worl~ By understanding and controlling the process parameters, AFM can be applied to an impressive range of finishing operations, providing uniform, repeatable, predictable results. In abrasive flow machining two opposed cylinders extrude a semisolid abrasive media back and forth through passages formed by the workpiece and the tooling (Figure 1). The process is abrasive only where the flow is restricted: the extrusion area. The machining action compares to a grinding or lapping operation as the abrasive media gently and uniformly hones the surface or edges.
